The upcoming SBS drama shows Park Shin Hye's high school days, when she goes on her path to becoming a tough gangster, and then her days as a doctor when she reunites with Kim Rae Won. Lee Sung Kyung can also be seen in a cute high school uniform - looks like you can expect some rivalry there.

Daebak! This is awesome! Park Shin hye and Lee Sung kyung practically trading their typical onscreen characters, and they're doing it so well. And Kim Rae won is cool as ever. Also, was anyone reminded of that scene in "Heirs" where Lee Min ho and Shin hye were eating pies in the motel after they were stranded for a night in California when the scene in 3:55 came in? :D
